This mod introduces astronauts' health management to KSP. You have to consider health implications when building vessels, planning and executing missions. It covers various factors affecting health including living space, microgravity, radiation, diseases, accidents and more. It is highly customizable and works well alongside most popular mods.

Unsupported releases for older KSP versions: for KSP 1.4.x, for KSP 1.3.1, for KSP 1.3.0, for KSP 1.2.2
Features
Every kerbal has Health Points (HP).
Maximum HP increases with kerbals' level. A newbie has 100 HP while a 5-level kerbal has 150.
Kerbals' HP change, including in the background and in timewarp, based on a range of factors such as living space, presence of crewmates, gravity, and specific ship parts. E.g., a level 1 kerbal will typically survive 11 days in a 1-man pod before becoming exhausted and turning into a Tourist.
Kerbals need time to recuperate at the KSC between flights to restore full health.
If a kerbal's health goes under 20%, he/she is exhausted and becomes a Tourist. They will go back to work when health grows back to 25%.
If a kerbal's health falls to 0, he/she dies!
Kerbals experience radiation, both cosmic and artificial, which permanently affects their maximum health.
You can protect from radiation by using shielding and choosing safer mission profiles. Planets and moons can reduce radiation with their magnetic fields, atmospheres and occlusion, to various degrees.
Kerbals may fall sick, have health accidents, panic attacks and other contingences
When kerbals level up, they can acquire quirks that affect their health reactions, to the better or to the worse.
Health Monitor lets you check on all your kerbals in KSC and in flight.
Health Report in Editor helps design comfy and healthy craft.
A configurable low health alert will warn you when you are about to lose a kerbal.
Compatibility patches support a range of parts mods (see below).
All of these settings are easily changed or disabled in-game and with ModuleManager patches.
Health Factors
The following factors may affect kerbal's health:
Assigned (kerbal is on a mission): -0.5 HP/day
Confinement (scaled effect): -3 x / HP/day (Living Space is provided by most crewed parts, depending on their size, capacity, function etc.)
Loneliness (only 1 kerbal in the vessel, badass kerbals are immune): -1 HP/day
Microgravity (orbital or suborbital flight or under 0.1 g conditions, e.g. Minmus): -0.5 HP/day
EVA: -10 HP/day
Connected (having a working CommNet connection to home): +0.5 HP/day
Home (on Kerbin below 18 km altitude): +2 HP/day
KSC (kerbal is recuperating in KSC, i.e. available): +5 HP/day
These values, like most others in the mod, are adjustable in Difficulty Settings. They also depend on quirks of a particular kerbal. You can check current values for a specific crew member in Health Monitor.
Certain parts (Hitchhiker, crew cabins, and the Cupola + many provided by mods) can additionally reduce the effect of a health factor (Confinement in this case) allowing for much longer and healthier flights. It often requires EC though. Hab rings in some mods can help overcome Microgravity issues for long-term stations and interplanetary missions. All these features can be changed using ModuleManager patches.
Health Recuperation
Certain parts (such as the Cupola) provide Recuperation bonuses. If a kerbal receives, say, a 1% recuperation bonus, he/she will recover 1% of their lacking health (i.e. of the difference between their current HP and the maximum HP) every day. This change works in parallel with the normal health factors above.
Example: A 5-star kerbal (maximum HP = 150) currently has 40 Health Points and is in a vessel that gives him 1% recuperation. The vessel has 10 units of living space and he has connection and he has a crewmate. Therefore he recovers (150 - 40) x 1% = 1.1 HP per day and loses also (0.5 + 3 x 2 / 10 + 0.5 - 0.5) = 1.15 HP per day. It means that the marginal change balances out the "normal" change and his health will stay around 40 HP (27%) until the situation changes.
As you see, this mechanics may allow some kerbals to stay relatively healthy indefinitely. It may look cheaty, but the point is that: (1) there should be a way to design long-term missions without spamming crew space, (2) it requires a lot of heavy parts and therefore still difficult, (3) the balanced health level is usually far from 100% and may fall lower if circumstances change (e.g., new crew arrives and fills the station), (4) these bonuses require a lot of EC, (5) radiation still keeps mounting (see below).
Note that, since v1.1, Recuperation is not stacked and has crew cap. It means that one Cupola provides 1% Recup for 2 kerbals, 2 Cupolas give 1% for 4 kerbals (not 2%!), etc. If you have more kerbals than the crew cap, Recuperation will be split among them evenly (e.g. 4 kerbals with 1 Cupola will get 0.5% Recup).
Decay is the opposite to Recuperation: for every percentage point of Decay, your kerbal will lose 1% of their remaining health per day. Fortunately, it is very rare.
Radiation
All kerbals on missions are affected by radiation, which slowly but permanently reduces their maximum HP. Radiation is measured in banana equivalent doses (when you eat a banana, you get approximately 1e-7 Sv of radiation). 1e7 (10,000,000) bananas reduce max HP by 10%; 1e8 (100,000,000) bananas kill a kerbal. Currently, there is no way to reduce the dose, so plan missions carefully.
The amount of Radiation a kerbal receives depends on many factors. Most importantly, it is determined by their location. Many planets and some moons have magnetic fields that stop some radiation; atmospheres are also very effective in shielding it (see wiki for more). Being close to a celestial body helps screen some rays too. E.g., radiation level at Kerbin's sea level is 1,000 times lower than in interplanetary space just outside Kerbin's SOI. Cosmic radiation is also greater closer to the Sun. To check environment before sending astronauts, you can use magnetometers and Geiger counters provided by supported mods or embedded in advanced stock probe cores.
Being on EVA takes away all the protection your ship provides and dramatically increases radiation level. Artificial radiation is created by certain parts like atomic engines and nuclear reactors.
You can protect kerbals from radiation (both cosmic and artificial) by adding shielding to the vessel. It is provided by some parts, like structural panels, heat shields and mk3 cargo bays. These parts and most crew pods can be improved by adding Radiation Shielding to them in the Editor. You can never eliminate all radiation, but you can reduce it to non-dangerous levels.
Quirks
Whenever a kerbal levels up, there is a 25% chance that he or she will acquire a health quirk (unless he/she already has two). Discovering an anomaly can also grant a free quirk. These can be positive or negative and usually affect kerbals' vulnerability to various health factors and dangers. Chances of getting some quirks depend on courage and stupidity of a particular kerbal. The full list can be found in the Kerbal Health Wiki.
Random Events
Kerbals' organisms, like ours own, are not always predictable. Sometimes, not very often, you may see unexpected events that can impact your whole mission. Kerbals acquire (or lose) certain conditions as a result of these events. Having parts with a Sick Bay (such as the stock Science Lab) helps alleviate the symptoms.
Sickness: A kerbal can become sick and start losing health quickly. His/her crewmates may catch the disease too, including during the incubation period. This condition usually heals itself after some time, but it can also lead to a pneumonia, a really dangerous condition. Having Scientists or Medics aboard helps.
Injuries: A kerbal can immediately lose some health in an accident. Stupid kerbals are naturally predisposed to this condition. It may cause sepsis, which is mortally dangerous. Bring your kerbal home immediately or pray Kraken it will heal on its own.
Food poisoning: Kerbals are known for their love of snacks and they don't always wash their hands. Food poisoning may not be as bad as some other conditions on its own, but if dehydration develops, they will become unable to do any work at all and effectively turn into space Tourists until it passes.
Panic attacks: Though not posing danger to health per se, panic prevents kerbals from doing any useful work. At least it doesn't last long and courageous kerbals are less prone to it.
Conditions can be disabled or their chances and effects changed in game settings. You can also easily add, modify or remove conditions (see wiki for details).

Conflicts & Incompatibilities
Any mod, which can temporarily make kerbals Tourists, can conflict with Kerbal Health if both mods change kerbals' status and then turn it back. In some situations it may mean that your kerbals will remain Tourists indefinitely or become active too soon. Kerbal Health tries to fix some of these situations, but cannot prevent all of them.
It is recommended to disable habitation mechanics of USI-LS' (and other mods') as these largely have the same goal as Kerbal Health.
RemoteTech's connection state is not supported for the purpose of the Connected Factor status. This issue will be resolved once RemoteTech 2.0 is released. Meanwhile, you may disable both Connected and Assigned factors to keep balance.
Compatibility with Kerbalism hasn't been tested. This mod changes much of game's internal mechanics, so it can be incompatible.
Future Features
New mechanics: more various conditions, more quirks, radioactive planets, medical supplies, quarantine, and whatnot...
More fine-tuned effect of health on kerbals' capabilities
Maybe a different microgravity system
Radiation cure (very hard)
API for collaboration with other mods

Changelog

Have you ever said "I don't want to live on this planet anymore"? Now you can! We at Kerman & Kerman Orbit and
SurfaceStructures are proud to present you the all new product line for Kerbals who want nothing more than to live on another planet! We at Kerman & Kerman finally got out of the testing phase and now consider our parts to be usable.
This mod adds several new parts that are designed to be used in a planetery base for the Kerbals.This includes Habitats,
Greenhouse, Laboratory, a Cupola derivative, Command-Center and others. It is designed to fit with the other stock parts
and feel as "Kerbal" as possible.
Important update Note: To be compatible to KAS 1.0 the flexible corridor now consists of two separate parts. The active part is called "K&K Flexible
Corridor" it can now be connected by a Kerbal to any "K&K Docking-Port" or "K&K Corridor Docking-Port". It is not possible
anymore to connect two "K&K Flexible Corridor" parts with each other like it used to be before.

This mod redistributes the Community Category Kit and Community Resource Pack from @RoverDude and contains parts for Deepfreeze that are made by @JPLRepo and @MerlinsMaster. They are licensed under:

"SeaQuest KSP" :: Powered by Wild Blue Industries It's time to build that fishing gear. The ocean is becoming even more playable!
Carrying the legacy of my "The Spice" mod, this one seeks to attempt to fill a very well known void in KSP and to open another door to (mostly) untapped gameplay opportunities. SeaQuest gives the player more to do with Kerbin's ocean, and adds value to (large) planet mods or large installs thereof.
SeaQuest KSP builds upon the Wild Blue Tools core mod made and owned by @Angel-125. Currently, no new parts (specifically, no new part models) are on the roadmap for this mod. Pathfinder is recommended for installation in order to get the most out of SeaQuest. The "Lasso" scoop devices in Pathfinder will be the example fish catching devices. MOLE (Mark One Laboratory Extensions) is additionally recommended for the science aspect and the complete experience. This mod fits right into the subtitle of Pathfinder: "Space Camping & Geoscience," and is not meant to be a full mod on its own, but rather, to only be an expansion. What is a camping trip without catching a few fish and frying them?
Unlike "The Spice" (to those who know of and have tried it), mining, traveling and colonization aspects will not be chained down by a single habitable mystery planet and its OP handwavium engine stuff hoping to be found, but will be open to any and every planet mod with worlds capable of hosting life.
Fishes will not spawn and be visible and jump around, no. They are merely resources and may occur in any undisclosed number of oceans on varying compatible planets assuming the player has many planets with oceans installed.
Gameplay dimensions:
Fishing. With RNG!
Powered by the WBI OmniConverter module, fishing will actually require a splashed vessel to sit and wait for a solid haul of the chosen category of fish. There will be chances to catch a bonus, catch less, or even none at all.
TBA various classes of fish will be select-able and mine-able. Each class may require its own amount or size of time interval between catches.
Some classes of fish can or will be common to multiple worlds. Others can be rare and exclusive.
Economy
Every sort of fish has its price, weight, and amount per tank volume. By default, the tank templates will include a hefty ratio of Water or Classic Stock GrayWater for them to live in, but the water must be added separately when configured in OmniStorage (when available)... There is no penalty to not providing water for the fish but for roleplay's sake and "realism" would you keep fish in a dry, empty tank and expect them to live?
Floating and seaside bases become just a little more practical and their harvests can be sold for funds for your career.
Some classes of fish will be convertible to life support resources but the conversion process will involve varying fractions of waste output (convenient for buffing Fertilizer production or meeting other edge cases that need waste resources).
Science
A small host of LDEF-alike experiments focused on fish will be included. Some with very high demands. Most will have clones per unique compatible world for fresh science gathering per unique compatible world.
Planned Compatibility
Stockalike Station Parts Expansion Redux by @Nertea. (see 3.75m Aquaculture module)
Snacks! and Classic Stock by Angel-125
Stock planets (of course) and Outer Planets Mod. Other planet packs are TBD.
Supply and Demand by @Eskandare.

After discussion with @KospY, who is the author of the original idea, we agreed that I should take ownership over the mod to continue maintaining and developing it. Today, KAS is completely different from what KospY have made in 2015, but his idea is still here - we connect vessels in space! The forum thread for the initial version of KAS can be found here.
>>> Support me at Patreon if you like the mod!
Kerbal Attachment System (KAS)
This mod is another extension to the EVA duty of the kerbonauts. Now they can link different vessels together. Why linking? Well, how about transferring resources without docking? Or maybe two vessels need to stay together while not docked. Even more, this mod has active parts that can work as winches!
A great variety of links is supported:
Rigid. It's basically a simple strut, but kerbals can set it up or remove being EVA. Bring some of these things on your Mun base and reinforce the structure!
Rigid unlocked. It's still the same strut, but the joints are unlocked. It allows the vessels to move, while not getting too close or too far to/from each other.
Active rigid. Do you need to tow a vessel? If yes, then you need a tow bar. Only in KAS you can find advanced models of tow bars that can assist steering. Greater towing speed means more fun!
Flexible. It's an elastic cable that can stretch at some extent while still forcing the vessel to stay together.
Active flexible. It's still a cable, but now its distance can be changed either via an EVA kerbal, or via a remote control GUI. Basically, it's an electric winch.
Resource transfer. Zero structure force in exchange to an ability to have some free length. Link the vessels up to the maximum distance and move the resources via a convenient GUI (a way more convenient than the stock one!).
Almost any type allows remotely docking the vessels. Once docked, the vessels become a single base where the stock game functionality can work.

If you are a native speaker of any other language, please, consider adding your translation. Simply ping me in PM if you're willing to do so, and I'll do my best to help you. And don't be shy if your speaking English is not very well, what is required is your native language skill - we're trying to be funny in KAS part descriptions, it can be challenging to make a proper translation. And if you think you don't need extra help, try reading this link - it may save you a lot of efforts while translating KAS.
Support
You can support this and the other of my mods on Patreon. This is where I post my ideas, prototypes and the features development progress.
Other useful mods for EVA
If you want doing EVA comfortably, you really should consider adding these mods as well:
Kerbal Inventory System (KIS). Now you can build and upgrade vessels in EVA!
Easy Vessel Switch (EVS). No more guessing how to switch to "that vessel" - simply point and click!
Surface Mounted Lights. Too dark for EVA on the other side of the moon? Problem solved with these ambient lights!
How to install
Recommended:
Install and run CKAN.
Search for "Kerbal Attachment System" or just "KAS", then install the mod.
Occasionally run CKAN client to update KAS (and other mods) to the latest version.
If you follow this path, then all the KAS dependencies will be updated automatically. It may save you a lot of time during the update.
Manual:
Download the ZIP archive:
From CurseForge.
From Spacedock.
From GitHub.
If you have an older version of the mod in your game, you must delete all the old files first! Do not just copy over, this will likely result in compatibility issues.
Unzip the release archive into the game's GameData folder.
Note, that names of the folders must be exactly like in the archive or the mod won't work.
The release archive contains the minimum versions of the required dependencies: ModuleManager and CommunityCatgeoryKit. If your game has better versions, do not overwrite!
Verify the installation: the mod's LICENSE.md file must be located at <game root>/GameData/KAS/LICENSE.md.
>>> Important notes to KAS v1.0
Starting from KAS v1.0 a completely new branch of the mod is released. The changes are conceptual, so parts from v1.* are not compatible with v0.6.4. However, to not break the save games, the old v0.6.4 parts are included in the v1.0 release. These parts are renamed to have a "LEGACY" prefix - this is how you can check if you're using the old parts. The old parts are no more supported and are provided "as-is". No bugs will be fixed there, regardless to their severity. If you cannot use a legacy part due to a bug, then it means you should start using the new parts Moreover, the old parts are provided only temporarily. The support will be completely discontinued on February 1st, 2019. Please, make sure your save games don't have the old parts after this date.

Zee's "Probes Before Crew" CTT Overhaul KSP Version 1.6.1 - Jan 19 2019
Hello everyone! I would like to present a CTT overhaul I have been working on since the release of 1.6. I call it Probes Before Crew, and it does what it says on the box; it places remote technologies far ahead of crewed alternatives on the tech tree while also placing greater significance and reward on crewed actions and achievements as a result. The intent of this mod is to make your career campaigns balanced, intuitive, and challenging by ensuring all the mods that you are using interact with one another in a coherent way on the tech tree. If you would like to have a look through my notes and read a more verbose explanation of my changes and the reasoning behind a lot of my choices, I will place them in a spoiler below. = = = = = The Highlights:
Generally speaking, all tech categories were stretched out a bit to enjoy all the new leg-room the CTT gives us.
Probe Cores come first, and now possess their own form of crew report, the 'Telemetry Report'. Cockpits don't show up until T4, and Command Modules must wait until T5.
A purpose-built, completely optional Contract Pack by Zee that overhauls the economy of the game and aims to make it more challenging.
Antenna, Electrical, Science, Utilities, Thermals, ISRU, etc; they have all been re-positioned [and in some cases mildly tweaked] with careful consideration of one another.
Science Overhauled and Re-balanced; Experiments are less tedious, more spread out across the tech tree branches, and place higher significance/reward on the experiments that REQUIRE a Kerbal be present.
PLEASE NOTE: Science rewards have been reduced overall. I recommend you do not set the Science slider below 70%, and that's under the assumption you are at least using DMagic Orbital Science (If not, consider moving the slider higher).
This chart is not an exhaustive list of all the vanilla parts I've moved, it just highlights the big players and gives you a general idea of their new relationship to each other.
This chart serves as the guideline/reference point for mod support patches as I add them. = = = = = Supported Mods (so far) "Supported" Mod means I have gone through every part, science definition, and entry/VAB cost for that mod and placed everything in a way as to be consistent with all other supported mods.
This means a unified, intuitive, and logical experience as you progress through the tech tree with all your favorite mods.
This is a work in progress and there a ton of mods I want to support so the list will grow over time.
As of right now, Probes Before Crew covers:
Vanilla Parts.
Making History Expansion.
Pairs well with Strategia.
Works out of the box with KAS and KIS.

If you use mods not listed its completely fine, they just might unlock at odd times relative to the rest of PBC until I add support.
If there are mods listed that you don't use, no worries! This mod ignores making changes to mods you don't have, and none of them are required. If there is a mod you would like to see supported by PBC, just let me know and I'll see what I can do.
The next patch in line is Mk IV Spaceplane System.
= = = = = Original Built-For-PBC Contract Pack If you choose to use my contract pack, quick facts you should know:
All you need to do to "enable it" is install Contract Configurator by Nightingale. That's it!
Another mod by Nightingale, Strategia pairs very well with this contract pack. Highly recommended.
This contract pack is purpose built for this techtree, so I'm not releasing it as a separate mod and I offer no support if you try to use it without PBC.
The vanilla tutorial and exploration contracts are disabled when running PBC Contracts. Mini-milestone rewards will provide smaller rewards. They will no longer shower us with easy money in the early game!
Any vessel you land on a given body that meets all pre-reqs will be a valid candidate vessel to complete the "Return Home" parameter; leaving you to do so at your own pace with any valid vessel you want.
PLEASE NOTE: Just like the notice above about Science, I recommend you keep your funds slider at least at 80% if using PBC Contracts. The economy has been overhauled and made much more challenging.
You will feel the difference between 100% > 90% > 80%.
= = = = = Download / Installation
1. You must be using KSP Version 1.6+. KSP Versions prior to 1.6.0 are not compatible.
2. ModuleManager is a dependency that must be installed first.
3. CommunityTechTree is a dependency that must be installed first.
4. If you wish to enable my Contract Pack, Contract Configurator must be installed. This step is optional.

Capture objects by a magnet or a hook.
Surface Mounted Stock-Alike Lights for Self-Illumination. EVA work on a dark side is always challenging. Stock lights are designed for illuminating objects at large distances and they are inconvenient when you only need to get some ambience light around your base or station. These surface mounted lights fill the gap:
Small and compact omni light source can be easily mounted where needed. It takes little or none energy and gives enough light to see the parts you're working on.
Low energy spot lights let illuminating objects at small distances (5-10 meters) without producing annoying glares.
Fun facts
The "E-SD80 Electric Screwdriver" part has a real life prototype: NASA engineers use the "Pistol Grip Tool". And this tool is different from a regular mechanical screwdriver which many people believe they can use. Next time you'll ask yourselves "why, the heck, this tool is only usable by an engineer?", just read the article.
Videos
Using KIS, KAS, and Planetary Base Systems modules you can build a nice looking Minmums base. Use it for refueling your station and drones.

Localization
For now KIS supports the following languages: English, Russian, Spanish, Italian and Chinese. If you feel you can translate from any of them into your own language, feel free to do it and suggest the translation to the author. The Localization tool may be a great help in your translation endeavour. In nutshell, if you want to translate the mod, you need to get the localization file (either English, or Russian), and provide your own strings for the language of your choice.

Introduction
Interplanetary Colonization represents one of the largest technological and logistical challenges on the horizon for manned spaceflight.
USI's Modular Kolonization System (MKS) provides a huge array of new gameplay systems and supporting parts to support the experience of designing, building, and maintaining interplanetary colonies in Kerbal Space Progam.
For over three years, MKS has been the definitive Colonization mod for KSP, with continued refinement of the parts and core systems (including the resource system now integrated in the stock game) based on extensive community feedback and continued development and design.
MKS is not a parts pack. It is a gameplay mod that adds a massive amount of end-game content for KSP, and can serve as the perfect capstone for your career save. It can be soul crushingly hard, and as unforgiving as gravity. But it can also be an incredibly rewarding gameplay experience, bringing back that sense of wonder and accomplishment that many of us remember from our first Mun landing.
If you want a parts pack where your idea of a colony is landing a single ship and call it a day, this is probably not the mod for you. If you want something that transforms your gameplay, and gives you unapologetically difficult goals where you have to juggle planning, logistics, and the harsh constraints imposed by space, then you will likely get as much enjoyment playing MKS as I have received building and designing it.
Features
MKS adds a rich array of new features to support the challenge of building interplanetary colonies, including:
A huge assortment of parts suitable for surface and orbital bases and stations, drawing inspiration from real-world parts and concepts from Bigelow, NASA, and others.
A clear progression of parts, from simple outposts and mobile bases to larger manufacturing complexes and permanent colonies.
Extended ISRU operations with more resources and more complex harvesting, refining, manufacturing chains, and new mechanics.
Discoverable resource lodes for more interactive resource harvesting and exploitation
Customizable and field-configurable converters and harvesters to allow post-launch customization of your colony.
Tools for handling large bases, such as ground tethering and automated resource transfers for disconnected bases
Tools for building out your base In-Situ with harvested resources, whether it's by expanding and kitting out modules, or through in-situ construction via the bundled Ground Construction mod by @allista
Parts and tools for contructing bases including weldable ports, magnetic couplers, and heavy construction equipment via the bundled Konstruction mod.
Parts for mobile bases via the bundled Karibou Expedition Rover
Expanded Kerbal traits and effects in support of Kolonization
Comprehensive and seamless integration with USI Life Support, including life support, habitation, and homesickness.
Kolony rewards, providing ever increasing efficiencies as well as tangible bonuses in career mode, as your Kerbals gain experience colonizing other planets and moons.
The ability to support permanent colonies as well as ark-ships as your Kerbals expand their knowledge and become more experienced with off-world colonies.
Part disassembly and recycling
Wireless power transmission and Geothermal wells
Equipment wear and tear along with manual and automated maintenance tools
And much more!
FAQ
I hear MKS is really complicated - is that true?
MKS has significant depth and breadth, but provided you don't try to do everything at once, you will find the learning curve can be pretty reasonable. Start with life support, and don't get fixated on trying to build everything at once. The patterns learned with a small base quickly scale for larger ones.
What about documentation?
Thanks to @dboi88, MKS enjoys full KSPedia documentation.
There's also an excellent community maintained wiki available here.
MKS Documentation even has its own development thread here.
I can't seem to fit a 100% self sufficient base in a single launch - what am I doing wrong?
Building a self sufficient colony is hard. Like... REALLY hard. It's going to take a lot of launches and a lot of work. The idea of MKS is that it is not about plunking down a base and being done. Rather, it's the journey to get to that point that is the fun bit. So yeah... you are going to need a few more rockets.
I can't find a place to create my base that has all of the resources!
Good. Now you get to enjoy some of the challenges that result from resource constraints. Do you ship things in? Do you set up multiple bases? Or use low-efficiency harvesting to get trace materials and salvage the rest from scrapped components?
I feel overwhelmed... I try to make a base, and it seems I just need so many different parts!
Start small. Start with just a habitation module or two and ship in supplies. Then add some agroponics and ship in fertilizer. Once you get those down pat, you are ready for more complex systems.
I am still lost - where can I get help?
Ask in this thread. A lot of the folks here have been using MKS in their games for years, and are a pretty friendly lot.
This looks amazing, and I didn't have any plans for my weekend anyway - where do I get this stuff?

** New ** Vessel to vessel crew transfers!
Ship Manifest is a tool to manage your ship's "things".
I originally started with Crew Manifest as a basis for this work. My great thanks go out to vXSovereignXv for creating Crew Manifest, and Sarbian for contributions to and continuing maintenance of Crew Manifest.
I've now re-imagined it into Ship Manifest, Crew transfers are now only a small part of what SM can do. Ship Manifest moves crew, Science and Resources around from part to part within your ship or station. It also manages docked vessel refueling, hatches, deployable Solar Panels, antennas and lights. Kinda like your Ship's bridge...
Ship Manifest has a LOT of flexibility and a lot of Options. So much is available that is NOT seen in a default installation (Realism mode set ON by default) that you may be missing a lot of what SM has to offer. Please go to the Settings Window to see what options are available, and play with them. You will be surprised at the number of features that exist in this tool. I believe in choice, so you can configure SM to be pretty much exactly what you want. You want a "realistic" experience? Check. You want to be a god and chafe at realism mode restrictions? Check.
I also invite suggestions for things you would like to see.
Current Version: 5.2.1.0, 17 Mar, 2018 -- Download: SpaceDock | CurseForge | GitHub (all releases). Also supports CKAN and KSP-AVC for your convenience in updating.
NOTE: This version of SM is NOT backwards compatible. It will not work on KSP version 1.3.1.
License: CC BY-NC-SA 4.0. Original license on Crew Manifest was do as you want. I felt the original and contributing authors deserve due attribution, since this is a derivative work.

No Mod Dependencies!:
Ship Manifest is mod independent. You don't need any other mods to use Ship Manifest. However, if you install the mods below, Ship Manifest provides specific support for their features.
Toolbar, by blizzy78. This mod is the "original" and a great alternative to the stock toolbar.
Connected Living Spaces (CLS) by codepoet. This mod provides the player with graphical information on livable spaces in a ship. It shows you where you could go internally on your ship.
Module Manager. This mod allows you to extend the configurations on your parts. Used by CLS.
RemoteTech. This mod overhauls the unmanned space program and makes antennas much more important. Very powerful mod.
DeepFreeze. This mod provides part(s) for cryogenic freezing of kerbals for long duration flights. JPLRepo has taken over maintenance of this mod.
USI Kolonization System (MKS/OKS) Inflatable Modules. Very cool mod for compacting your trips and station builds.
KSP-AVC. This mod checks your installed mod versions against the mod's latest version. Let's you know when you need to update.
CKAN. The Comprehensive Kerbal Archive Network (CKAN) Package Manager (CKAN) is a multi-platform app that manages nearly all your mods from one clean executable. Performs installs, updates, and uninstalls of your mods automatically.
NOTE TO CKAN USERS: don't expect support for installs via CKAN. if the CKAN install fails, contact the CKAN folks, NOT me.
What's New:
Version 5.2.1.0 - Release 17 Mar 2018 - KSP 1.4.1 Edition

Easy Vessel Switch (EVS)
The stock game doesn't care much about the camera stabilization when you switch between the vessels. You can walk in EVA, enter a pod, and end up with a camera looking in the sky. Or you may want to take a closer look at some part of your big station, but the camera focus is bound to the station's center of mass, and the part of the interest is far away form it.
This mod can help you solving these troubles! With EVS:
...the camera will stop jumping around randomly. There are two modes of stabilization that allow preserving the view in the scene (switch with F7)...
...you're able to focus the view on any part of any vessel with a simple mouse click (with O hold, it's configurable)...
...a new active vessel can be selected by simply holding ALT (configurable) and clicking on the vessel you like...
...the basic info of a vessel can be quickly seen by simply hovering over it (with ALT hold)...
And this mod speaks 4 major languages in case of some of your kerbals are picky in this sense.

You can support this and the other of my mods on Patreon. This is where I post my ideas, prototypes and the features development progress.
Other useful mods for EVA
If you want doing EVA comfortably, you really should consider adding these mods as well:
Kerbal Inventory System (KIS). Now you can build and upgrade vessels in EVA!
Kerbal Attachment System (KAS). Need to link two vessels? Just send out your kerbals EVA! Don't forget to update their inventories, though.
Surface Mounted Lights. Too dark for EVA on the other side of the moon? Problem solved with these ambient lights!
How to install
Recommended:
Install and run CKAN.
Search for "Easy Vessel Switch" or just "EVS", then install the mod.
Occasionally run CKAN client to update EVS (and other mods) to the latest version.
If you follow this path, then all the EVS dependencies will be updated automatically. It may save you a lot of time during the update.
Manual:
Download the ZIP archive:
From CurseForge.
From Spacedock.
From GitHub.
Unzip release archive into the game's GameData folder.
Verify the installation: the mod's README.md file must be located at <game root>/GameData/EasyVesselSwitch/README.md.
Note, that all the names must be exactly like in the archive or it won't work.

The Gold Standard!
Version 1.5.2 (2017/06/18)
(Now with full SCANsat and Galileo's Planet Pack Compatibility!)
This mod adds the pursuit of gold and an extremely rare resource called Unobtainium to the game!
Gold Ore now appears on planets/moons
Gold Ore can be mined and smelted into Pure Gold with the Smelter
Return either Gold/Gold Ore back to Kerbin for profit
Gold is heavier than Gold Ore, which is heavier than Ore
Full integration with Vanilla drills and scanners
Vanilla Drills and Surface Scanner available slightly earlier in the tech tree
Only 8 parts (Under 10Mb download), low memory usage.
Get over that mid-career fund grind in a fun and challenging way!
What is Unobtainium?
Unobtainium is an extremely valuable resource that generally spawns on high-G and extremely distant worlds.
You can mine Unobtainium using the vanilla drills without needing a converter in-situ.
Drills mining Unobtainium operate much more efficiently with both a scientist and engineer aboard.
Unobtainium is a little more dense than gold, so ensure to bring adequate Dv!
Finally a monetary reason to land on Eeloo, Eve, Moho/Icarus, or any of the other seldom visited worlds!
This mod is not meant to be an easy cash cow; rather, a difficult alternative to contract spam.
There is no gold on kerbin, and be careful when choosing a mining site as only deposits of >2% (mini drill) or >1.5% (large drill) will yield gold ore.
The gold ore can be returned for an okish profit, but be aware that gold ore is basically 9/10s ore. So there are obvious benefits to smelting in-situ. The Smelter needs power, cooling, and an engineer to function at its full capacity.
Pure Gold is, by design and irl, HEAVY!
Feel free to post any working ship/base designs!
Note on returning with your space booty: Land near or on the space center to avoid diminished returns.
Supported mods:
- Scansat
- Galileo's Planet Pack

Introduction
"Kerbal Mods Overhaul" (KMO) is nothing more than a set of patches initially made to cope with the personal desire to simplify/modify a number of very popular mods, MKS in primis, in order to bring a slightly different gameplay experience to KSP.
KMO has initially been made exclusively for myself, however, since the number of patches has greatly increased over the time, I have eventually decided to make a public release of this mods overhaul for anyone that may be interested in such a reconfiguration work.
Disclaimer
This mod is NOT an updated version of MKS-LITE, it should rather be seen as a new gameplay experience for standard MKS (and related mods) with fewer resources, a simplified production-chain, changed part functionalities and full support for ExtraplanetaryLaunchpads resources, production chain, Survey Stations and Workshops.
Thus, this mod is NOT a tutorial mod for MKS beginners (that was the main purpose of MKS-Lite). If you just want to play an easier version of MKS in order to get your hands dirty and get to understand some basic mechanics, RoverDude has already implemented an optional patch that allows you to disable the requirement for machinery and get a gameplay experience closer to the one provided by MKS-Lite.
In addition to that, this mod does not include any part, asset, config file or anything else from any other mod.
Kerbal Mods Overhaul (KMO) is currently WIP.
Patches and Changes
I would like to make this mod as much configurable as possible, thus, I will try to add any suggestion/request into a patch, either optional or not. Please, ask for patches for supported mods only (see below). You may also ask me to create a patch for stock parts, however, the changes have to be related in some ways to the mods reconfigured by KMO.
This is a non-exhaustive list of the main patches and changes applied by KMO (v0.4):
You can opt-in or out some patches in order to get a personalized gameplay experience in accordance with your personal taste (PatchManager required).
See the individual .cfg files if you want to know more about the part specific overhaul.
Example of a fully self-sufficient planetary base below in Spoiler. You can see how the colonization parts have been reconfigured and appreciate the new gameplay design, which allows you to create smaller and easier-to-run bases.
Supported Mods
Below you can find core and optional mods supported by KMO. Core mods are the ones for which my reconfiguration work has initially been made for and so they have the biggest amount of patches available. Optional mods nicely complete the gameplay experience (you should NOT install them ONLY if you have some serious RAM/hardware issues).
Core mods:
Modular Kolonization System (MKS) made by RoverDude
USI Life Support (USI-LS) made by RoverDude
ExtraplanetaryLaunchpads (EL) made by skykooler and taniwha
PatchManager made by linuxgurugamer (you need it in order to enable/disable optional patches)
Optional mods:
OSE Workshop (KIS Addon) made by ObiVanDamme and Aelfhe1m*
KeridianDynamics Vessel Assembly made by EleusisLaArwall
*If you install this mod, also consider installing Kerbal Attachment System (KAS) and Kerbal Inventory System (KIS), both made by KospY, winn75 and IgorZ.
Notice: Always Remember to install all dependencies for the mods you use!
Installation
You can either:
Download KMO from Spacedock and then copy and paste the content of GameData into your KSP GameData folder.
OR, Download it directly from CKAN!
Notice: This mod includes version checking using MiniAVC. If you opt-in, it will use the internet to check whether there is a new version available. Data is only read from the internet and no personal information is sent. For a more comprehensive version checking experience, please download the KSP-AVC Plugin.
Notice 2: The latest version of KMO (v0.4.1) works only in KSP 1.4+ and with EL 6.0+ installed.

I always thought that science-points lose a lot of their value in the endgame once you have unlocked the entire tech-tree, which is why I made this mod. With Kerbal R&D you can spend science points to improve the stats of the parts you have already unlocked in a career game. At first the investment will be rather small, but the cost goes up exponentially so you will always have a good reason to bring back every last bit of science from your missions.

At the moment you can improve the following stats:
Dry mass of all parts (reduced mass of a part when empty)
Atmospheric and vacuum ISP of Engines (improving their fuel efficiency)
Fuel flow of Engines and RCS-Thrusters (increasing their maximum thrust)
Torque of reaction wheels
Charge rate of solar panels
Crash tolerance of landing legs
Battery capacity
Efficiency of Generators (eg RTGs)
Efficiency of Resource Converters
Safe deployment-speed of Parachutes
Maximum internal- and skin-temperature of all parts
Fuel pressure (capacity of fuel tanks)
The upgrades are tracked separately for each part and vessel, which means any research you do doesn't affect your ships and stations already in orbit. The cost of each upgrade and the improvement it will bring can be tweaked for each part via simple configuration files.
You can download the latest version of this mod from GitHub
1.15 (for KSP 1.4.2): https://github.com/mmoench/KRnD/archive/1.15.zip

1.13 (for KSP 1.2.2): https://github.com/mmoench/KRnD/archive/1.13.zip
This mod requires the mod Module Manager to work.
Please note that this mod is not 100% compatible with other mods which modify parts at runtime (eg TweakScale or InterstellarFuelSwitch).

If you are running a successful space agency, you will be flying to Kerbin-Orbit a lot. The Kerbal Space Transport System (or KSTS) will allow you to record launches of your transport rockets and planes to be used in automated missions later. It will allow you to transfer resources, crew-members and even deploy brand new ships directly into orbit. And because the cost of launching your payload is only as high as the cost of the mission you've previously recorded, you will benefit greatly of building reusable space planes without the hassle of landing them by hand every time.
You can for example record the launch of a space-plane and deploy a payload with a mass of 2.5t at an altitude of 286km before returning back home:
Afterwards you will be able to pick this recorded mission-profile and launch new vessels with a mass <=2.5t into an orbit with an apoapsis below 286km for only the cost of the fuel used by your space plane:
The new ship can be deployed at any orbit of your choosing that is within range of your mission-profile or right next to an existing reference-vessel, making your life in low-kerbin orbit much easier:
Features:
Record transport- and deployment-missions for rockets and planes.
Deploy new ships directly to Kerbin-Orbit (must have less or equal the mass of the payload from your reference mission).
Transport resources to vessels in Kerbin-Orbit (provided they are in range and have compatible docking-ports).
Use multiple transport missions to construct new ships at space stations in Kerbin-Orbit.
Transfer kerbals to and from vessels in Kerbin-Orbit.
Compatible with KRnD (newly launched ships will always use the latest part-upgrades).
Compatible with CLLS (modifications on vessels and crews are communicated via game-events).
In-Game help which explains how to get started and how it works.
Third Party Support:
StageRecovery: With this mod installed the total cost of your recorded flights is reduced by the value of successfully recovered boosters.
Known Incompatibilities (this mod skips the usual launch phase, any mod which depends on this might not work correctly):
ModularFuelTanks (tank-configuration does not work)
USI Life Support (some timers connected to the launch-time don't work)

Starting from Beta9 it's OK to use the new parts in the carrier games. Any new version of the Beta build is guaranteed to be compatible with your save games. You're encouraged to use as many parts from the mod as you can. And your feedback is very welcome!
The old parts (KAS 0.6.*) will be eventually deprecated. Once the 1.0 version is out, the legacy parts will be in the package for 3 months, but then they will be completely removed. You'll be able to manually install them from CurseForge from the older archives, but any issues will be refused. The only right approach is using the new parts. If you choose to use the old parts, it's your responsibility to make them working.
KAS 1.0 is a direct descendant of KAS 0.6.0, but it's not just another version of it. New KAS inherits the main idea of connecting two vessels into one, but does it in a different way. All code has been re-written from scratch, new parts designs were invented, new models developed, and physics has been significantly re-factored.
Here are main points in KAS 1.0:
All connections between the vessels are physical. They have mass and volume, and they interact with the world's physics.
New parts are engineering wise correct. I.e. they look and work as they would behave in a real world (at the extent the game allows it).
New KAS should be easy to use by third-parties. Ideally, it should be a no-brainer to create own KAS-like part or interact with KAS from the other mods. KAS API is being developed, and the docs will be published soon (here is the very first preliminary version).
Full feature parity with the old KAS is not expected but the goal is to cover all aspects of joining vessels together. Since it's a beta for now avoid using these parts in your main game. While parts design is pretty stable the exact properties may change (e.g. break force or minimum length).
Current plan of development
TJ-1. Rigid joint part that makes a durable fixed connection to another vessel. DONE.
TJ-2. Rigid joint part that makes a durable connection that keeps some flexibility at the connection points. DONE.
Extra: TB-60. Rigid joint that designed specifically for towing vessels. DONE.
HJ-1. Rigid joint built of two hydraulic cylinders that allow changing length of the link after the connection is done. DEPRECATED.
JS-1. Socket to connect with rigid links. DONE.
RTS-1.Part that allows connecting vessels at greater distances with a flexible pipe. It doesn't provide any structural strength. Used for transferring resources. DONE.
PCB-1. It's a portable cable brace. Basically, it's just a durable rope between two parts: you cannot stretch it but in all other directions the parts can move. DONE.
W-1. Light winch. It's a replica of old IW-50 on the new code base. DONE.
W-2. Heavy duty winch. It's a replica of old RW-50 on the new code base. DONE.
Hooks, harpoons, and magnets are in design stage for now. POSTPONED to the release.
Installation
Download this binary form Github.
Delete old KAS-1.0 folder from GameData folder if any.
Unzip folder KAS-1.0 from the archive into GameData folder.
KAS 1.0 is totally independent from the old KAS and doesn't conflict with it. You may use both.

I'm finding as I am gaining more hours and experience playing Kerbal Space Program, that I am starting to impose rules, or at least methods of play on myself. For example, I don't like using additional reaction wheels in most aircraft (and I usually turn off stability-except for long distance cruising). I feel like my planes should at least be able to fly with as little aid as possible. That is not an absolute (I break that rule for some of my really weird ones), but it is an ideal.
I know some people only play in stock. Others may eschew certain mods or only use mods like Realism Overhaul or FAR that make things harder.
So, what is your limit? Are their certain parts you won't use or certain building methods you stay away from? Do you not allow yourself to revert flights? What line (if any) do you draw for yourself and why?

With the work I've been doing on Ship Manifest, and the recent breakthrough in renaming and changing the professions of our beloved kerbals, along with the recent mods that actively manage kerbal professions via other means, I decided to breakout the Roster portion of Ship Manifest and expand it into a new Plugin. Since Ship Manifest essentially deals with Flight operations on a vessel, the Roster Feature always felt like an "afterthought". It was part of the original Crew Manifest, which I used as a basis for Ship Manifest over a year ago, but now with the way Ship Manifest has evolved, it makes more and more sense to separate and expand on this feature.
I've already got a working shell running with the base functionality of the Roster in Ship Manifest as my starting point.
However, this plugin will not end up looking like a rehash of that. My thoughts are as follows: This initial post will be updated as more info and a definition is added.

- Added Salaries option to Settings, also in settings you can set salaries to be paid monthly or yearly.
- Salaries are set via Training - Experience Tab in the GUI. Default value is 10000 funds.
- Salaries are deducted monthly or yearly, but if you do not have enough funds then the kerbals who aren't paid will go into a contract dispute mode.
- Contract Disputes occur when kerbals are not paid their salary. Each pay period the kerbals who aren't paid will ask for a payrise (which goes up each time they aren't paid).
All un-paid salary will accrue each time they are not paid.
The user can accept the payrise and the kerbal will continue to work for you. However, this will only occur for 3 pay periods. At the end of the third occurrence of them not
being paid the kerbal will go on strike (Become a tourist). Until such time as they are paid all owed money.
- A Contracts Window is available to see all kerbals that currently are in contract dispute and allow you to accept payrise, decline (they go on strike). Or if you have
funds available you can re-pay them all owed monies and they will go back to work for you.
- Each month or year (salary period) funds are checked and if there are enough contract disputes are automatically resolved.
- Added KerbalLifeSpanInfo including Age and lifespan processing setting for each kerbal.
- If this setting is on all kerbals in the game will age over time and eventually die from old age.
- If the Repawn kerbal option is on in the main game settings then they will respawn when the die (but as a new freshman again).
- If you also have DeepFreeze Mod intalled then freezing a kerbal will stop the aging process whilst they are frozen.
- Each Kerbals age is shown in the Attributes Tab for each kerbal and the main roster list. But the age cannot be changed.
- Refactored code, cleaned up code style, standardized variables and usage.
If you use DeepFreeze, you will need the latest version above to work with Roster Manager.

Roster Manager
- Roster list - From the Roster list, you can select the kerbal to manage
- Attributes - This section allows you to change the kerbal's attributes (like in Ship manifest, but more control and no limit on which vessel. Will be affected by realism...
- Records (career file) - This is where all management functions will reside. In the personnel file we can manage:
o Salaries - Kerbals donÃ¢â‚¬â„¢t work for free, so some cost for each kerbal should exist. We will pay a salary to each kerbal on the roster, on a Biweekly/ Monthly/ yearly basis, (configurable). Salaries can be adjusted for realism and playablility.
o Stats Editing - Editing stats. You can change the Primary profession, name, and other properties of your kerbal.
o Notes - A simple editor that allows you to add notes to your kerbal
* Training- Training is a means to increase your kerbal's experience through training. Training can consist of time spent away from flight learning specific tasks, or via Simulations such as in HoloDeck mod.
- Cross Training (multi Profession) It will be possible to maintain multiple professions. Through training and flights, you can increase a specific profession by selecting that profession for a given flight.
o Experience - Experience is gained thru flights. With RM, experience can also be gained thru training on specific tasks and thru Simulator training using HoloDeck. Training will increase the experience level of your Kerbals in the profession for which the training occurs.
o Flight / Simulation Log - Flight history and Simulation history will be stored in your Kerbal's personnel file
-Vessel flown
-Dates of filght
-Results
-Accomplishments
o Crew Performance - Crews that stay together fly better together. It will be possible to improve the performance of a given crew through training and Simulations performed together. Kerbals with more time together will perform better on a given flight.
o Accomplishments/Achievements - using Other addons, accomplishments can be gathered and added to your Kerbal's personnel file.
o Medals - Medals for significant achievements can be earned.
o Medical / Psych - Your Kerbal's abilities can be impacted by their medical condition and sanity. While no insane kerbals are possible (yet), (no suicides, sorry), their mental state will impact their skills. Things like time in space alone, traumatic events like crash landings and such can affect their abilities for certain periods of time.
Kerbal Type and Status are now here. Since medical typically approves kerbal for flight status... It made sense to include it here... ther are restrictions to flight status, so if you pick unusual settings, the Medical Team will warn you against these rash choices....
- Recruitment/Termination - It will be possible to hire/fire Kerbals. Fired Kerbals will be removed from the game permanently (Will impact the game save).
- Scheduling - It will be possible to schedule kerbal crews and crew rotations, vacations, have impacts to crew due to illness, and medical issues.
- Settings
o Reputation/Currency
o Realism
o Scheduling
o Recruitment / Termination
- Persistence - This Mod will change the game save. This allows the management of many parts of the kerbal's experience, profession, and accomplishments.
I'll be placing this in a PDF on the GITHUB site I will be creating to make it easier to read..
The Idea behind this mod is to extend the Kerbal experience, provide some control, and provide an ecosystem around them. I intend to leverage the available mods around this theme, and attempt to maintain compatibility as much as possible.
At the moment I'm looking at leveraging and compatibility with CrewQueue, HoloDeck, KerbalStats and other mods.
Suggestions and comments are welcomed.Your thoughts/suggestions are welcome.
If you can think of a better Name for the Mod, I'm certainly up for discussion on that as well...
Thanks!

Supported KSP version: 1.2.2, 1.3.0
License: GNU GPLv3 (included)

I've tried to make focus on realism as much as I was able to research the subject so the default settings assume that all kerbals including tourists are trained astronauts wearing G-suits.
Pilots are more trained than others, of course.
The following G-effects are simulated:
Blackouts/redouts
Loss of color vision a.k.a "greyout"
Tunnel vision as G rises
Kerbals grunt while they perform AGSM (anti-G straining maneuver) and take a heavy breath after
Blood beating in kerbal's ears on redout (wear headphones with good bass and you'll feel it)
G-LOC (G-induced loss of consciousness)
Kerbal deaths of a sustained over-G
G forces have different severity in four directions: upward, downward, backward, forward, so you may find that a kerbal launched in a rocket stands more G than a kerbal piloting a plane upside down on a circular trajectory.
Kerbal's specialization also affects how much he can stand.
You can use this mod together with KeepFit by timmers_uk. In this case kerbals' fitness will affect their ability to withstand over G effects (supported by G-Effects v0.2.3+ and KeepFit v0.8.3.3+).
Download from SpaceDock (for KSP 1.3.0)
Download from SpaceDock (for KSP 1.2.2)
If you don't have a joystick it is recommended to use with Analog Control Continued mod for the best aircraft experience
Installation:
Save the old G-Effects.cfg file if you have changed it. Delete previous version of the mod. Place contents of the zip into your KSP/GameData folder.
You'll have to enter the config params you have saved manually into the new version's configuration file because it has several important changes.
Stock integration:
Stock g-meters and notifications correspond to the mod's state. If you don't need them you may disable "Kerbal G limits" in the game's settings, the main mod's behaviour won't be affected.
Kerbal experience and other stock g stats are still ignored.
Configuration:
Configuration of the mod is done via G-Effects.cfg file. Look through it to have an exhaustive description of its parameters.
The major parameters of those you can fine tune are:
A common kerbal's ability to resist G effects
Restrict video and audio effects to IVA mode only
Severity of effects of G forces applied from different directions
How much specialization help a kerbal to resist an over-G
Disable G-deaths
and more
The sounds are still a little WIP so you always have an option to disable them via config file if you find'em too annoying.
Anyway, after trying the mod please respond to the poll in this thread for I knew which way to move further. Would also appreciate any comments or suggestions.
Known issues and limitations:
G-forces caused by a ship's rotation don't affect because they are not likely to be severe enough to induce any significant effects.
Effects are calculated for the active vessel's crew only. You can switch to another vessel and back and have effects applied as if they have just started.
Planned features:

New, it's well forgotten old. I have not played a career in KSP much over a year, and having recently undertaken, I faced that a very useful mod by xEvilReeperx are outdated and has not been updated for a long time. I wrote to the author and he gave me permission to adapt it to the new version, and here it are. Sure, i need feedback about how it work from community.
When is is it time for science?
Who knows! The game provides no feedback when you've crossed a biome barrier, a new crew report is available or when you've forgotten to run a goo experiment. Wouldn't it be cool to stop guessing?
(c) xEvilReeperx
What it does:
Features:
Audio and visual cue when science is available
Configurable science filters for experiments
Configurable option to stop warp when an experiment becomes available
science threshold to ignore low value reports
Optional SCANsat integration
Dependences: Toolbar (do not forget to do button visible )
Installation & Usage
Download the plugin and extract in your KSP directory like any mod.
Actual use in-game is simple. When the button is lit, at least one experiment onboard matches your criteria. If the flask is animating, then a new experiment just became available (animation will stop when you have viewed the new experiment list). There are lots of per-experiment settings to choose from.
left-click - to open the list of currently available experiments,
right-click - opens the options menu,
SCANsat support
Enable SCANsat integration in the additional options menu
With this option enabled, you will only receive biome-associated alerts if you have mapped that portion of the planet's surface
Non-biome specific alerts will still occur as normal
Known Bugs:
if you transmit science report(s) using a transmitter's action menu, the reports queued for it won't be taken into account until transmission is complete
[not a bug] Available experiments and report values may suddenly change when going on EVA. This is because your Kerbal may be in a different "situation" -- for example, sitting on the pad might trigger an EVA alert for LaunchPad but you go on EVA and the alert stops. This is because the game considers the Kerbal to be "flying" while holding onto a ladder while in the air.

Hi, I'm a newbie to KSP, so sorry if this question seems dumb.
When I was using the demo version of the game, I was able to set objects (such as the Mun) as targets and get maneuvering tips.
But I just started using the full paid version & I can't select anything as a target now. Left-click used to do it. Now NOTHING!
Also, I was able to set maneuver nodes in the demo version & now I can't do that either.
Are these functions disabled to make it more of a challenge or am I doing something wrong?
Thanks in advance for answering me.

hello I've been a player of ksp for a long time and I think it would be good to add a multiplayer. I think these multiplayer features would be the best and serve for ksp:
first off adding friends this is simple we have a online username account that well be used to pull up the players account page and you can add friend or join game which means the player is playing with the other players.
groups this can be made by any player and a group can serve as just for friends or it can serve for a certain amount of players only like 20 multiplayer players and the user wants 10 he can do that you can also just do you and a friend.
this multiplayer wouldn't be a mod it would be built in the game.
I hope you consider making this you'll make me and so many other people happy thank you ksp team.
any other feature the ksp founders would like to add this is unlimited because they made the game.
my opinion I've played a lot of games and I've seen that multiplayer is a lot of fun it can get boring playing a game by yourself this adds a new experience in gameplay there is gonna be dog fights, wars, racing, flying together, operations and so much more this little add will give a huge amount of fun and gameplay and its gonna be so many kingdoms of players are gonna arise and buy the game I know because I have friends and a brother me my friends and my brother we buy games we like that have multiplayer ones that don't we usually look for another one but I really like this game and so does my friends and brother I really think this would help. thank you for your time.
for the gamers of ksp
multiplayer would add so much fun and a huge experience it would be epic and fun think of the gameplay that would be possible wars and big wars, operations you plan, huge fleet of planes flying, and so much more with our imagination's and what we want to do In the game we can do some pretty awesome stuff thank you community for reading.

Hi
So I just sold off my RX 580 graphics card and is currently using my backup GT610, and I am wondering if there are any ways to make ksp playable on that graphics card without sacrificing too much. I have a watercooled R5 1600x CPU and 16 gigs of ram, and I am currently getting around 4 fps with settings maxed out. What can I do to get my framerate above 30 fps while sacrificing the least amount of detail?
Thanks!

I cannot find any issues related to this, so I thought I would ask. Steam version, downloaded and reinstalled multiple times over the years. Always worked fine, until recently. Game loads up just fine; no hangups on the load screen at all. Main menu works, in addition to the other settings and such. Loading up the Space Center works as well, with no issues until I enter the Hangar/VAB or the Launchpad/Runway.
Hangar/VAB: Cannot see the vehicle being built, at all. I can still select parts, and every menu and button works, yet all I see is a black screen Unless I mouse-over where the vehicle would be to see the highlighted part, I cannot physically see the vehicle.
Launchpad/VAB: UI and instrumentation load up. Much like the Hangar/VAB, unable to see the vehicle itself, nor the scenery of the game. I can still launch the vehicle, and all the control are just as responsive, yet again: I cannot see the vehicle. It should be noted, that I can still view the orbital map mode, and the tracking station still works.
I have tried to validate files and have reinstalled multiple times, but to no avail. No mods or anything. Kinda sucks, but has anyone had any luck or experience?
Specs: Windows 10 (64-bit), i5-3230M CPU @ 2.60GHz, 8 GB RAM, GeForce GTX 660M.
UPDATE: No progress made, but sometimes I have observed that when i revert a flight back to launch, for a brief moment I am able to see the craft and scenery before, once again, it goes black.

So I've seen these optimal engine charts for helping select the best (set of) engines for a mission/craft, based to the TWR and Delta-V requirements, and (tried to) use them extensively to design long range missions and the like.
Until I noticed that these are all horrifically out of date!
https://meithan.net/KSP/engines/: for KSP1.1.1
https://imgur.com/a/OS6bk: for KSP0.23.5
So I am looking for some up-to-date charts, some tips on an at-home version of meithan's chart, or failing that, contact information for meithan so I can help update his web-app.

Closed Loop Life Support (CLLS) is a simple life support mod which aims at simulating a small, self-contained system for keeping Kerbals alive during long voyages through space. It adds a new resource "LifeSupport" which is consumed by Kerbals at a rate of one unit per day. If your crew runs out of life support they will die. To prevent this dire fate, this mod adds new life support containers to increase the maximum mission time as well as life support generators, which will allow you to create self sufficient ships and stations, provided you have enough electricity.

1.1 (for KSP 1.2.1): https://github.com/mmoench/CLLS/archive/1.1.zip
Features
Kerbals will require life support to stay alive (1 unit per 6 hour day).
All parts with crew capacity will hold a small amount of life support (3 units per crew-slot).
Kerbals on EVA will take 1 unit of life support from the ship and put it back once they return, giving you a maximum EVA duration of 1 day.
Kerbals which have run out of life support will die.
Life support can be extended with life support storage containers.
For longer missions life support generators can be used to generate life support. This allows the creation of fully self-sufficient interplanetary ships and bases.
The production-rate and thus the energy consumption of life support generators can be tweaked to avoid wasting resources.
The life support usage and production is tracked for all ships, even in the background and during time warp.
Technical Details
This mod keeps track of the life support values of all vessels, even those which are not currently active. This is done by caching their last known consumption / production levels as well as their remaining resources. When an event is triggered that changes the game-world (like launching a ship, modifying an (inactive) vessel, saving the game or running out of life support), all vessels are updated. This should make it compatible with other mods which manipulate inactive vessels (like KSTS) while consuming only very little system resources.
